Do You Still Need Hearing Protection with a Suppressor? Of course, you do. At least, you do in most cases, with very few exceptions.
When you first clamp a suppressor on your rifle and touch off a round, the difference can feel pretty drastic, and it can be easy to fool yourself into thinking that you’re doing zero damage to your hearing once a suppressor goes on. The sharp crack drops to a manageable thump, and you wonder if ear pro is truly optional. The honest answer from my own experience (and mistakes) is that while a lot of suppressors out there have some insane dB reduction ratings, it’s pretty rare that a gun/suppressor/ammo combo drops every shot below safe levels for repeated exposure.
Let’s understand why I think many newer gun owners incorrectly assume suppressors are a replacement for hearing protection on the range with a suppressed gun.
How Loud Are Suppressed Guns?
A suppressor works (as most of you already know) by trapping and slowing the high-pressure gases that blast out behind the bullet. Those gases, traveling at many times the speed of sound (often faster than the bullet itself), generate a ton of noise, which in its own right and in the right circumstances, is part of the fun.
Quality cans can typically reduce the peak sound by 20 to 35 decibels. That matches what a good set of earplugs or over-the-ear muffs will deliver if used properly. Unsuppressed centerfire or even rimfire gunshots often exceed 160 dB at the muzzle and stay well over 140 dB at your ear. With a suppressor in place, centerfire rifles and pistols commonly land between 130 and 140 dB.
Unsuppressed gunfire is like standing next to a jet engine at takeoff. A suppressor brings it closer to a chainsaw, pneumatic impact wrench, or ambulance siren, which, as most of you will intuitively know, are noises you don’t want to be exposed to for very long without some sort of hearing protection (even though all those sounds are awesome to listen to). The National Institute for Occupational Safety and Health flags anything at or above 140 dB as risky for immediate damage with impulse noise. Many suppressed setups sit right around or just under that line, depending on caliber, barrel length, ammo, and environment.
Personal Experience with Centerfire Shooting
In my own range time, I almost always still wear hearing protection when shooting anything centerfire. Sometimes, when testing a new suppressor, I’ll pop my earpro off to hear “what it sounds like,” but outside of that, you won’t catch me not wearing earpro when there is anything other than a suppressed rimfire gun on the firing line. The reduction from a suppressor makes sessions more comfortable and less fatiguing, in addition to the protection your earpro provides.
While I’d personally recommend you always wear proper hearing protection at the range, I only skip ear pro when the entire platform is so quiet through its combination of features (and the ammo I’ve selected) that I have personally deemed it hearing safe. That decision never comes lightly and only happens after careful testing on that specific setup. I love listening to music, so I don’t want to ruin that for myself.
Many newer gun owners, especially ones who are just now dipping their muzzles into the suppressor world, often see big marketing numbers or hear a suppressed shot and assume the job is done. They read about 30-plus dB reductions that a lot of these new silencers are producing, and picture total silence.
In reality, those ratings come from specific test conditions, often measured at the muzzle, not at the shooter’s ear. By the time you throw in variables like the wide variation ammo choice, barrel lengths, gas systems, and most importantly, shooting environment, you wind up with a lot of tolerance stacking that doesn’t often match or even meet the manufacturers’ stated dB ratings, which might be OSHA hearing safe in their specific set of conditions.
How I Determine If a Suppressed Setup Is Hearing Safe
I usually start by understanding the benchmarks. OSHA guidance sets 140 dB peak as the threshold where impulsive noise like gunshots should not exceed for a single exposure without additional protection. If you’re looking for some common household comparisons to similar impulse noise, you can think of popping a balloon, power tools like non-brushless drills and saws, squeaky dog toys, and, surprisingly enough, smoke detector noises, including the little chirps that tell you when the battery needs to be replaced.
I’m sure none of you wear hearing protection for any of these events. When it comes to guns, when I know I’ll be exposed to those noises, the safest approach that I tend to use is to treat anything both supersonic and centerfire as a no-go zone for taking your earpro off.
Subsonic .300 Blackout on a short barrel with a high-performance can can sometimes dip low enough outdoors to be considered comparable to some louder 22lr semi-autos. However, these are typically handloaded or very expensive factory ammo and thus are not common for what you’d find most people shooting for a typical casual range session.
Even then, consider variables that change the equation. I’d guess that most people are shooting at indoor ranges, and that environment bounces sound around and raises the intensity of the baseline levels. Nearby shooters add to the mix, and you can’t always know what will come out of one of their range bags next. Most shooters, myself included, default to protection anyway because the margin for error is slim and hearing loss is permanent. All it takes is one shot, and you can pretty much “hear” that you’ve damaged your ears for life.
To reiterate: Certain quiet combinations come close to hearing-safe territory for limited amounts of shooting. Well-tuned subsonic .300 Blackout, subsonic .45 ACP or 9mm, and even other subsonic centrefire cartridges, and optimized .22 LR rigs sometimes measure low enough that a single range session outdoors feels manageable without plugs or muffs.
Even then, most experienced shooters keep some form of protection handy just in case. The American Suppressor Association and medical groups agree that suppressors lower the risk but do not replace traditional hearing protection.
Best Practice: Combine Tools
The smartest approach, in my opinion, is to always be acutely aware of how you’re pairing your firearm, suppressor, and ammunition with quality ear pro. Outdoors, I almost always like to run electronic muffs or well-fitted in-ear plugs with high-pitch filters, and then I can enjoy clear communication plus extra safety against my range buddy’s “dinner bell” muzzle brakes.
Indoors or during long-range sessions with full-size rifle cartridges, I’m typically doubling up with plugs under muffs, which more or less just allows me to deal with the repeated noise for a little longer. This layered method should drop your effective exposure below damaging thresholds and, at the very least, will reduce your fatigue from the repeated concussion.
If you’re new to suppressors and are the “I need to hear it for myself” type, Silencer Shop’s team often recommends starting with versatile options that perform across hosts. For rimfire or pistol use, the SilencerCo Sparrow 22 is an affordable, lightweight choice that has an established history and reputation for a strong reduction in sound on .22 platforms. It typically runs $296 and works well for new users building suppressed habits (everyone should be shooting suppressed) while supporting your ear pro routine.
For multi-caliber flexibility on rifles or pistols ( a few of you mentioned this when we talked about dedicated .22LR suppressors), the SilencerCo Omega 36M offers modular performance that handles 5.56, 9mm, and larger calibers effectively. But you’ll pay for the flexibility, and it’s priced at $993.
So while it’s expensive, it does give you one can that adapts as their collection grows, always with the understanding that ear protection stays part of the system, specifically because multi-caliber cans are really only good at suppressing one diameter of projectile – maybe two if you include rimfire guns.
So… Do You Still Need Hearing Protection with a Suppressor?
I love suppressors. I think they are probably one of the more important firearm accessories you can buy today because they deliver meaningful hearing protection by cutting the source noise, but they do not make gunfire silent or risk-free on their own.
In most real-world (not lab test) scenarios with centerfire rifles and pistols, you still benefit from wearing ear pro alongside your can. The combination preserves your hearing longer, improves your overall shooting comfort, and lets you focus on shooting rather than bracing for the blast that still exists on a lot of platforms with factory ammo. So keep those muffs on and those plugs in as often as you can.
We’d of course like to hear your thoughts and experience on the subject. What do you consider “hearing safe” at the range when it comes to suppressors? Are there any times that you shoot unsuppressed guns without hearing protection, for example, when hunting? We’d be interested to hear what you think in the comments! And of course, if you’re still not sure what kind of suppressor would fit your setup best, SilencerShop has a handy “suppressor finder” tool that will narrow your choices down.
